GradleUp/shadow 9.0.0-rc3 on GitHub

Important

This release is a major update from the 8.3.x series. The plugin has been fully rewritten in Kotlin, bringing significant improvements to maintainability, performance, and future extensibility. It introduces many new features, enhancements, and bug fixes, and includes several breaking changes. Please review the changelog carefully and consult the new doc site before upgrading.

Added

Add PreserveFirstFoundResourceTransformer. (#1548)
This is useful when you set shadowJar.duplicatesStrategy = DuplicatesStrategy.INCLUDE (the default behavior) and want to ensure that only the first found resource is included in the final JAR.
Fail build if the ZIP entries in the shadowed JAR are duplicate. (#1552)
This feature is controlled by the shadowJar.failOnDuplicateEntries property, which is false by default.
Related to setting duplicatesStrategy = DuplicatesStrategy.FAIL but there are some differences:
- It only checks the entries in the shadowed jar, not the input files.
- It works with setting duplicatesStrategy to any value.
- It provides a more strict check before the JAR is created.

Changed

BREAKING CHANGE: Rename ShadowJar's enableRelocation to enableAutoRelocation. (#1541)
The Command Line options are also updated:

--enable-auto-relocation          Enables auto relocation of packages in the dependencies.
--no-enable-auto-relocation       Disables option --enable-auto-relocation.
--fail-on-duplicate-entries       Fails build if the ZIP entries in the shadowed JAR are duplicate.
--no-fail-on-duplicate-entries    Disables option --fail-on-duplicate-entries.
--minimize-jar                    Minimizes the jar by removing unused classes.
--no-minimize-jar                 Disables option --minimize-jar.
--relocation-prefix               Prefix used for auto relocation of packages in the dependencies.
--rerun                           Causes the task to be re-run even if up-to-date.

Mark Action parameters as non-null. (#1555)

Removed

Remove JVM default compat stuff. (#1556)
